I plugged in your config and troubleshot it for about an hour, no good....the output below shows it 'should' work...but sometimes with PacketTracer you have to be careful, you could be doing everything right, but PT will say your wrong...I will plug the configs into a lab enviroment Monday or Tuesday and let you know how it goes then.

Dont get too caught up in getting this to work, as I understand it in the real world you would have a dedicated FR Switch, not a router mimicking one. PT still didnt take the no frame-relay inverse arp, but I got the config below working in the on real 2811s.
